CVE-2020-36766 [LOW] kernel: memory leak in drivers/media/cec/core/cec-api.c
kernel: memory leak in drivers/media/cec/core/cec-api.c
An issue was discovered in the Linux kernel before 5.8.6. drivers/media/cec/core/cec-api.c leaks one byte of kernel memory on specific hardware to unprivileged users, because of directly assigning log_addrs with a hole in the struct.
A flaw was found in cec_adap_g_log_addrs in drivers/media/cec/core/cec-api.c in the Linux Kernel. This issue may allow a local attacker to leak one byte of kernel memory on specific hardware to unprivileged users, directly assigning log_addrs with a hole in the structure, causing a kernel information leak problem.
Mitigation: Mitigation for this issue is to skip loading the affected module HDMI Consumer Electronics Control framework driver "cec" onto the system until we have a fix available. This can b
